Castellan Crowe
Castellan Garran Crowe is the simultaneously both the Captain and the Brotherhood champion of the Grey Knight Purifiers. Ironically, aside from the standard Matt Ward dickery, the Crowe is probably one of the only Grey Knights (other than Brother-Captain Stern. FUCK YEAH) that has not earned the rage of the Knight players.
Why is he is not part of Ward's Dick Club?
It is partially because of this fucking weird sword. A daemon sword (WTF!?) called the Blade of Antwyr. Crowe acquired guardianship of the sword because it had mindfucked and ass raped every other guy who used the sword but has not affected him. This pleases many [writefags] who have grown tried of the fuck overused evil-thing-corrupting-good-thing cliche of many occult genres. The fluff is fairly straightforward and states that Crowe is constantly brings him physical and spiritual peril as the sword attracts chaos to it wherever he goes cough--One-Righ--cough, constantly trying to corrupt him in the process.
